Not necessarily.  If for instance most of the values fit in int2, then
the upper zero bytes would be fodder for compression.  (If they *all*
fit in int2 then of course he's missing a trick...)  The fact that they
are successfully using row compression on their old platform indicates
that there's some win available there.
